Schedule
When F9 4707 flies
F9 4707 flies IAD to ATL without a single fixed slot. Its most common scheduled departure was 06:10, used on 82 of 334 flights, with 06:00 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 4707 runs 19 points worse at 70.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
F9 4707 quarter by quarter
F9 4707 did not run the same all year. Its best quarter was Jul–Sep 2025 at 81.8% on time and its weakest Apr–Jun 2026 at 57.8%, a swing of 24 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
- Jul–Sep 202592 flights81.8%
- Oct–Dec 202591 flights72.2%
- Jan–Mar 202660 flights68.3%

By weekday, F9 4707 did best on Tuesday at 79.5% on time and worst on Sunday at 53.2%. Each day rests on about 48 flights, so a gap of 26 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 4707 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,242 reported delay minutes.
- 36%Late-arriving aircraft
- 33%National Airspace System
- 29%Carrier
- 1%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 8,242 reported delay minutes here, that single category outweighs weather by 36 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 8,242 delay minutes reported on F9 4707.
Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 534 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 334 flights under F9 4707 in the data flew IAD to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 334 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
